Specification of Letters Patent.

Application filed May 21, 1917. Seria1No.' 170,114.

To all whom it may concern:

Be it known that I, AMATo N. SAMMARONE,

a citizen of the United States, and a resident of- Akron. in the countyof Summit and State] of Ohio, have made certain new and usefulImprovements in Armature- Core -plu pports, of which the following is aspec fiicat on.

My invention relates to improvements in arinature'core supports, and itconsists in the combinations, constructions and arrangementshereindescri'bed and claimed.

An object of my invention is to provide an armature core support whichis made of pressed steel metal parts secured together in such a mannerthat a circulation of air is maintained thereby cooling the core.

A further object of my invention is to provide an armature core supportwhich is strong in comparison with its weight.

A further obj eot of my invention is to prO- I vide an armature coresupport which is so formed that the core may be placedon the support orremoved therefrom with the greatest facility.

Other objects and advantages will appear in the following specificationand the novel features of the invention will be particularly pointed outin the appended claims.

My invention is illustrated in the accompanying drawings forming part ofthis ap-- plication, in which:

Figure 1 is a sectional view of one form of the armature core support.

Fig. 2 is a section on the line 2-2 of Fig. 1.

Fig. 3 Fig. 2.

Fig. 4 is a perspective view of the core support.

Fig. 5 is a sectional view of a modified form of the core support.

is a section ,on the line 3-3 of Fig. 6 is a section on the line 6-6 ofFig. 5. Fig. 5, and,

Fig. 8 is a section on the line 88 of Fig. 5. The present application isa continuation in part of a prior application, Serial No.

1424.7 filed Jan.25, 1916.

In carrying out myfinvention I provide a series of stamped metalportions,thus, in Fig. 4, 1 denotes in" general'onejfof' these stampedportions, the other portions being extending flanges 5.

have a portion 5 at each end, which is par-.

7 is a section on the line 7-7 of Fig.

' shown at 3 and 4,respectively. It will Patented se a24,191s.

be observed thatthe portion 1 has an arc- J V shaped bodyportio'iiprovided with radially allel with the axis of the core support,and a shoulder 5". It also has a bearing'surface 5, there being slots 6at the ends of the bearing surface. The section 1 has a pressed key-way7, and is provided with ribs 8 which are pressed from the sheet metaland which stiffen the flanges 5. I

These flanges each I cured thereto by means of keys 13 such as thatshown in Fig. 2. The outer portion of the stamped key-ways 11' enter thekey- V we s'7.

he core consists preferably of laminated sheets 14 secured together inany'suitable manner to form a unitary structure. The sheets are providedwith cut-away portions 14: arranged to fit over the bearing surfaces 5.It is slipped on over the end of the support and rests on the bearingsurface 5, the latter keeping the core from turning. The position of thecore is determined by a split ring 15, which'may be put in positionbefore the core is slipped on, if it is slipped on from the right handend, another split ring 16 being sprung into position to hold the coreon its support.

The portion 5 forms a bearing for the commutator bars 17 which may beheld in any suitablemanner. Instead of using the support shown in Fig.4, I may make use of the sleeve itself- To this end the pressed key-ways'11 are cut to permit the use of spring rings 18 and 19. The laminatedplates are slipped on over the sleeve and rest upon the body portion ofthe sleeve, due to the fact that slots 20 are provided in said laminatedplates to receive the pressed kegways 11. These key-ways form ribs on te outer side of the sleeve which enter the slots 20, as stated, therebykeeping the core from rotating.

It will be seen that I make use of either form of the support or bothtogether. In using the form shown in Fig. 4 alone, the shaft is securedto the support by a key which may enter the pressed key Way 7. The corela is secured to the support as already described,

I am aware that various modifications might be made, but I consider asmy own all such modifications as fairly fall Within the spirit and thescope of the invention.

I claim '1. An armature core support consisting of a sleeve made up ofsections, each section comprising an arc-shaped body portion. havingradially extending flanges, the flanges of adjacent sections abuttingeach other, integral brace members extending from said flanges to thecurved body portion, means for securing the sections together, anannular core arranged to slip over the radially extending flanges, andmeans for securing the annular core to the flanges.

2. An armature core support consisting of a sleeve made up of sections,each section comprising an arc-shaped body portion having radiallyextending flanges, the flanges of adjacent sections abutting each other,means for securing the sections together, an annular core arranged toslip over the radially extending flanges, means for securing the annularcore to the flanges, said last named means comprising a split springring at each end of the annular core arranged to fit in grooves in theradially extending flanges, and integral braces extending from saidflanges to said curved body portion.

3. In an armature core support, a series of stamped sheet metalsections, each sec tion comprising a curved body portion having radiallyextending flanges at its ends and being provided with pressed bracesextending from the flanges to the body portions intermediate of itsends, the radially extending flanges of adjacent sections abutting eachother, means for securing said flanges together, said flanges beingprovided with a series of slots, an annular core arranged to slip overthe outer edges of the abutting flanges, and a spring ring at each endof said annular core arranged to fit in said slots for holding said corein position.

4. In an armature core support, a series of stamped sheet metalsect-ions, each section comprising a curved body portion having radiallyextending flanges at its side and bein provided with pressed bracesextending troin the flanges to thebody portions intermediate of itsends, the radially extending flanges of adjacent sections abutting eachother, means for securing said flanges together, said flanges beingprovided with a series of slots, an annular core arranged to slip overthe outer edges of the abutting flanges, a spring ring at each end ofsaid annular core arranged to fit in said slots for holding said core inposition, and a pressed key-way in one of said sections arranged toreceive a key for securing the sleeve to the shaft.

5. An armature core support comprising a sleeve having a series ofradially extending flanges, an annular core having grooves arranged toreceive the flanges, said flanges extending beyond the ends of the core,in-

tegral brace members on both sides of each of said radially extendingflanges, and means for securing the core to the flanges, said last namedmeans comprising a split ring at each end of the annular core arrangedto fit in the grooves in the radially extending flanges.
